United States Patent PILE FABRICS William Rollin Keen, Media, Pa., assignor to Collins & Aikman Corporation, Philadelphia, Pa., a corporation of Delaware Application December 29, 1953, Serial No. 400,892

1 Claim. (Cl. 139--399) This invention relates to pile fabrics. More particularly, it is concerned with pile fabrics having an integral lining suitable for use in tailoring and in the manufacture of draperies and the like where it is usual to have a lining material at the back surface.

The back side of pile fabrics, as ordinarily constructed, have a rough and unattractive appearance, and it has therefore been necessary heretofore to attach to them, as by sewing, a separate backing or finishing lining of smooth material such as silk, rayon or the like when used for purposes other than upholstering. The application of the linings in this way was time consuming and entailed the employment of skilled workers at high pay, which added very considerably to costs in tailoring and in the manufacture of the draperies and the like.

The chief aim of my invention is to overcome the aforementioned drawbacks and ditficulties. This objective is realized in practice, as hereinafter more fully disclosed, through provision of a pile fabric having a smooth and attractive finish backing integrally incorporated there with incident to weaving.

In the drawings:

Fig. 1 is a fragmentary more or less diagrammatic perspective view on a greatly magnified scale of the face side of the pile fabric embodying my invention, with the pile tufts and the component threads of the foundation weave spread apart to better show the manner of interlacement of said threads.

Fig. 2 is a generally similar view showing the rear face of the fabric; and

Fig. 3 is a view drawn to a much smaller scale and ghgwing the actual appearance of the rear face of the a nc.

As herein illustrated, my improved fabric has a foundation weave in which pairs of ground warp threads 1 and 2 are interlaced at spaced intervals with picks 3 and 4 of a weft thread as at 5. These warp and weft threads may be of inexpensive material such as cotton or the like. The pile tuft elements 6 and 7 at the face of the fabric are cut from pairs of pile warps and are looped under alternate weft picks 3 in the intervals between adjacent pairs of ground warps 1 and 2. The pile warps may be of wool, nylon, or any other fiber, for example. The covering for the back of the fabric is formed by pairs of auxiliary warps 8 and 9 which may be of silk, rayon, or nylon, and preferably of filament rather than spun yarns. As shown, these auxiliary warps 8 and 9, respectively lie outwardly adjacent the ground warps of each pair and are interlaced with different weft picks 3 at relatively long skip intervals lengthwise of the fabric. It is to be particularly noted that two U tuft elements 6, 7 of the face pile are engaged about each alternate pick 3 of the weft in the intervals between adjacent groups of the warps 1, 2, 8, 9. As a consequence of this construction, the foundation weave is substantially covered and concealed at the back of the fabric with creation of a smooth and attractive lining face having the appearance shown in Fig. 3 where the floats of the cover warps are indicated in white.

Having thus described my invention, I claim:

As a new product of manufacture, pile fabric having a foundation weave in which pairs of ground warps are interlaced at spaced intervals with picks of a weft thread, and in which auxiliary or back face warps respectively outward of the ground warps of each pair are interlaced at relatively long skip intervals with different picks of the weft; and multiple U pile tuft elements are looped about alternate weft picks in the intervals between adjacent groups of the ground and auxiliary warps.
